Figure 9. Collecting and testing vapor samples.
23. Test for CK
a. Snap both ends from a blue-band detector tube at the scorings and press the unmarked end of the detector
tube into the adapter as shown in figure 10. With the detector tube pointing down, compress the bulb sixty times.
b. Remove the detector tube from the adapter. If a yellow or orange color appears in the detector tube, CK is
present. Discard the detector tube and omit the test for G-agent (para 24) and the test for mustards or CX (para 25).
